Cool Some clarification questions about flipping the mixing manifold

....To clear a bottom mount turbo setup. Been doing a bit of reading/searching on this today and found some good threads that all seemed to end with OP saying "great I'll do that and take pics" then nothing. Or someone posts pics of mid-way progress or un-finished setup and I'm still wondering about how it all looks done.

So anyway, I have a BEGi S4 and need to relocate the lower rad on my 2001 to clear the IC piping. I was going to just buy the begi piece, but at $200 I feel its grossly overpriced, so DIY is in order. (or perhaps, a replacement lower rad hose if that would work)

I found a few decent pics of them flipped and/or re-worked:



I saw some by ARtech too and now somehow can't find them UGHHH

Also I saw mention of FM's molded silicone hose that supposedly goes around the IC piping and clears it, which I was very interested in, then saw someone mention that it doesn't work with BEGi kits?


Anywho, here's my question:
I don't have a re-route. I don't want one. IF there's a way for me to clear the IC piping without re-routing or re-doing or flipping anything I would gladly take that route. IF I can just use a different hose for the lower radiator routing I'll take that route if it will work.

Otherwise I might have to flip the mixing mani? if so, has anyone done it and retained both the little line that goes to the front waterneck, as well as the line that goes to the heater core?

This car is a ac/ps daily driver, and its staying that way. I want minimal modification game plan for IC piping and coolant hose routing to play well together. That is all.

Suggestions/thoughts/opinions but MOST IMPORTANTLY: PICTURES would be a tremendous help.

Thanks

I have the FM lower radiator hose. Would pics installed help to see if it will clear? Mixing manifold is in stock position.

No. No IC routing right now. NA. You would have to compare based on the just the photos.

No worries. Snap one if/when you get a chance. I'll try to eyeball it.

If I can get away with even just a $50 replacement hose I'll def take that route.

Thanks

I think I may have to flip mine though since I'll be using an ARTech bottom mount with my turbo. I didn't really think about it until I was putting the outlet back on a few weeks ago. Don't have my manifold yet so don't know for sure.

Mine is super ******* ugly because I didnt clean it worth **** or have enough amperage from my welder. I used a pre-bent hose to get to the radiator that I cut a bit off, I'll see if I left the hose number on it this weekend.



Thats the only picture I have of it. This arrangement requires a coolant reroute since it doesnt have a nipple for the line that comes off the thermo housing.

Why no thermo housing nipple? did you block it off? it should be right under your thumb in that pic

Yes I cut it off and filled the hole in. IIRC it was hitting the block or something. I wasnt going to use it anyways since my oil cooler goes to the upper rad hose, and I dont have TB heat.

Bump

Any more input? Anyone using the begi s4 without flipping the manifold or using the begi re-route?

Here is a quick pic of my FM lower hose


I don't have an engine , but should give you some idea of how it routes. Tried my best to ballpark where it sits from memory. Don't trust it 100%


I can try another angle if you'f like.

Edit: I think I had to trim it just a bit originally maybe 1/2in on one end. Can't quite remember.

ooh that's helpful, thanks. I'm starting to think the FM hose just might work for my needs

also I found the ARtech mixing manifold pics I was talking about just in case anyone's wondering:

Vlad, this is how I did mine. It may not look the best but it works really well. I will try and describe the pictures as best as I can.

This is the system all together with the turbo in place;

Here is a picture of the manifold itself, note where the AN fitting is on the back would be on the front and it was just a pressed in nipple that went to the thermostat neck.

This shot shows what I made to replace the factory hard line heater core pipe. It's just half inch copper piping. The short hose that is kind of weird shaped is actually a stock heater core hose I had laying around that I was able to use, works perfectly.

Here is just showing the heater core hoses.

Now what I did here to make sure it sealed without too much modification was to take the original hard line that has the o-ring on it and cut it and reposition it to point it towards the back of the car, these next two pictures show that. Then it got a little support piece that you see in the second picture.


And here is an overall shot of the whole setup, where the AN line is on the mixing manifold you probably wouldn't do, I am using those for the waterlines running to the wastegate.

Seems like a lot of work, but it really wasn't, and so far it has worked really well. The copper pipe has two clamps on it that use the exhaust manifold studs for mounting points.

Oh snap, I see. So you basically didn't modify the mixing mani at all, except for the little nipple that was going to the original waterneck. Nice. Yeah I remember checking it out way back when and I guess I forgot how you did it.

That's looking like it will be my backup plan if the FM water hose won't work.

Yes sir, no modification to the mixing manifold at all, just adding the AN fitting and modifying the hard pipe for the heater core.

I did a quick mock up of the neck and heater feed. I assume you want to retain the heater. Bolts go into cardboard to maintain location and ziptied the metal pipe down.


Then swapped it around to get ideas. This seems like an easy way of getting it all. Just need a couple taps, a -AN nipple, 90deg big-AN to nipple, short hose, and saw. Might have half that laying around.




EDIT: Now that I look at it more you may not have to cut the pipe. If you could rotate the 90deg -AN enough you could even use the ribbing on the hose to secure the short hose piece.

Forgive my shitty camera pictures and the 1.6

Wow thanks a bunch guys. That's looks like the hose just might work. Plan B will be what TZ and Ryan posted.

I'll post results when I do it.

I like Ryan's ingenuity, but it seems like way too many failure points getting introduced. It is awesome don't get me wrong. Just what can go wrong usually does.
